Paramore vocalist Hayley Williams wasn’t entirely convinced that anyone assembled at Voodoo Fest’s main stage on Saturday knew the name of her band. She made it her mission to change that. During an unflagging hour-long set, Williams announced, “We…are…PARAMORE!” more than once. Just in case anyone still didn’t know.

They are touring in support of their self-titled fourth album, which debuted at No. 1 on the Billboard 200 this spring. “We put out an album called ‘Paramore’ because that’s the name of our band,” Williams explained, “and we thought it sounded cool.”

She pronounced those in the audience who were seeing the band for the first time “fresh meat.” From go, she, guitarist Taylor York and bassist Jeremy Davis, backed by two auxiliary guitarists and a drummer, worked like they needed to prove themselves.

Their music is unfailingly energized, and so is Williams. An athletic dervish in constant motion, she skipped, pogoed, head-banged and strutted, as strong of a frontperson as was the band around her. She soon shed her leather jacket to reveal a midriff-baring top and skin-tight leather pants, all set off by a bright orange bob and a glittering black stripe across her eyes. She came across like Gwen Stefani crossed Dale Bozzio, the singer from ‘80s band Missing Persons, who also wore a raccoon stripe. Graft some muscle and crunch onto Missing Persons, and the result might sound like Paramore’s “Ignorance.”

Paramore’s best, most memorable songs strayed from the band’s standard, all-out formula. The stuttering “Ain’t It Fun,” with its rubbery bass and funky cadence, was a power-pop gem with a memorable refrain: “Don’t go cryin’ to your mama cause you’re on your own in the big world”; at its conclusion, Davis slapped at his bass down front alongside Williams. The ballad “The Only Exception” was also welcome change of pace.

But just as quickly, they dropped the big, bombs-away chords of “Pressure,” from their 2005 debut. Caught up in the moment and momentum, Davis executed a barrel roll over York’s back mid-song.

Williams, ever the underdog, said she realized their Voodoo set wasn’t really a Paramore show, but a Nine Inch Nails show; NIN was to follow Paramore on the same stage. Nine Inch Nails fans, however, could likely relate to the lyrics of Paramore’s “Last Hope”: “It’s not like I don’t feel the pain,” Williams sang. “It’s just I’m not afraid of hurting any more.”

At the end of their breathless set, Williams made one final plug: “For the last time, you have been at a Paramore show!”
